JOHN DAVIS, OF AURORA, ILLINOIS.

CABLE-CARRIER.

12) all whom it may concern:

Be it known that I, JOHN DAVIS, a citizen of the United States, andresident of Aurora, county of Kane, State of Illinois, have inventedcertain new and useful Improvements in Cable-Carriers, of which thefollowing is a specification.

The present invention relates tocablecarriers such as are employed instringing in aerial and other cables.

The object of the invention is to provide a carrier which will be simplein construction and economical to manufacture, while at the same timebringing about, by reason of its use, a considerable reduction in the issuspended from it by means of hangers which are positioned at regularintervals. It has been the practice heretofore in string ing such cableto suspend hangers or carriers from the messenger wire and to pull thecable through these hangers or carriers.

In carrying out my invention, I have pro vided a carrier which may beclamped to the cable and will move along with it instead of beingclamped to the messenger In this way, the carriers may be attached tothe cable at regular intervals as it leaves the reel on which it iswound and then properly set upon the messenger wire over which they willtravel "as the cable is pulled.

The full character and nature of the invention will be best understoodupon reference to the following detailed description taken in connectionwith the accompanying drawing, and the scope of the invention will beparticularly pointed out in the appended claims.

In the drawing, Figure 1 is a side elevation of the preferred form of myinvention,

viewed in position upon the messenger wire and clamped to the cable;Fig. 2 is a view at right angles to that of Fig. 1, parts being shown insection; Fig. 3 is a fragmentary sectional view similar to Fig. 2,illustrating an the position of the parts when a cable of smaller sizeis employed; and Figs. 4 and 5 are a side elevation and central verticalsection, respectively, of the third clamping member employed in thedevice. Throughout these figures, like characters refer to like parts.

Specification of Letters Patent.

Application filed July 29, 1910.

Serial No. 574,536.

Referring to the drawing in detail, it will be observed that the carrierin the preferred form of construction consists of a long strip 10 ofsuitable resilient material such as steel, Lent back upon itself at itsupper end so as to form a bearing for the grooved wheel 11, which ridesupon the messenger wire 12. At its lower end, the strip 10 is similarlybent back upon itself so as to form two clamping members 13, 14. At thelower end of the device, the strip is given a relatively large turn at15, so as to add to the resiliency of the members l3, 14. These lattermembers, together with the third clamping member 16, are adapted toengage the cable 17 and to clamp it securely in position. A clasp 1S,pivoted at 19 to the upper end of the member 14, is provided on itsunder edge with a plurality of teeth 20, which are adapted to engage themember 13 to hold the parts in variously adjusted positions. A slot 21is provided in the member 13 for the passage of the clasp 18. Theclamping members 13, 14, are curved outward slightly so as to form abetter seat for the cable 17 or 17. Likewise the upper face of the thirdclamping member 16 is gouged out so as to more closely engage the cable.The lower portions 22, 23, of the outwardly curved portions of themembers 13, 14, provide downwardly converging faces against which thefaces 24, 25 of the wedge-shaped portion of the member 16 are adapted toengage.

It will be seen that when the members 13, 14, are a considerabledistance apart, as in Fig. 2, these faces 22, 23, allow the member 16 todrop down, while, when the members 13 and 14 are drawn closer together,as in Fig. 3, these faces, cooperating with the faces 24, 25, cause thethird clamping member 16 to move upward. It will also be seen that theadjustment of the members 13 and 14 by hand brings about an automaticadjustment of the third clampingmember 16. By reason of this action, thethree clamping members 13, 14 and 16 readily adjust themselves accordingto the size of the cable which they embrace. In order to guide themember 16 in its toand-fro movement, it is provided at its ends withribs 26, which bear against the edges of the members 13 and 14. In orderto prevent the member 16 from dropping too far down, it is provided witha slot 27, through which extends a bolt 28 having a nut 29 secured toits threaded end. This nut is only screwed on the thread a shortdistance, thereby providing a loose pin and slot connection between theparts and allowing room for the separation of the members 13, 14.

It is obvious that the clamping member 16 might be guided and held inposition for actuation by the movement of the clamping members 13 and 11 through some other agency than the rib 16 and the bolt 28. This is adetail which may be readily modified without departing from myinvention. It will also be apparent that other means might be employedfor holding the clamping members 13, 14-, in their dili'erent adjustedpositions. It will also be apparent that these clamping members 13 and14: might be given their resilient action in some other way thanillustrated and that it is not necessary that they be all made of onestrip such as strip 10. It will also be apparent that the grooved wheel11, which is to ride upon the messenger wire 1:2, might be replaced byother suitable means. These modifications will readily suggestthemselves to one skilled in this art. In view of these possiblechanges, I therefore do not wish to be limited to the specific matterdisclosed, but aim to cover all such alterations and modifications bythe terms of the appended claims.

What I claim as new and desire to secure by Letters Patent of the UnitedStates is 1. A cable carrier comprising two relatively movable clampingmembers having converging faces, means for retaining said members, andthereby said faces, in different operative positions, a third clampingmember having a wedge-shaped portion embraced between said faces,whereby the adjustment of said first two clamping members automaticallyadjusts said third. clamping member, and a loose connection for limitingthe movement of said third clamping member to maintain it always inposition for actuation by said faces.

2. A cable carrier comprising a strip of resilient material bent backupon itself at both ends, at one end so as to form two clamping membersand at the other so as to form a bearing, a grooved wheel journaled insaid bearing, a clasp for retaining said clamping members in differentoperative positions against their resilience, a third clamping memberhaving a wedge-shaped portion embraced between converging faces of saidclamping members, whereby the adjustment of said two clamping membersautomatically adjusts said third member, ribs on said third member forguiding it in its to-and-fro movement, and a connecting means forlimiting the movement of said third member to maintain it always inposition for actuation by the movement of said two clamping members.

In witness whereof, I hereunto sign my name this 25th day of July, 1910.

JOHN DAVIS.
